The smartphone technology served as a crucial tool to reduce transmission rates and save lives
WA Notify—the Washington state’s COVID-19 exposure notification app—is scheduled to sunset May 11 in tandem with the end of the Public Health Emergency.
The smartphone application utilizes privacy-preserving Bluetooth technology to anonymously alert users they may have been exposed to someone who recently tested positive for COVID-19.
Since its launch in Nov. 2020, approximately 235,000 participants confirmed a positive test result in WA Notify, generating more than 2.5 million anonymous exposure notifications, preventing tens of thousands of COVID-19 cases, and saving lives.
Washington was one of the first states to implement exposure notification technology and consistently had one of the lowest COVID-19 death rates in the country, despite also being host to the earliest known domestic case of the virus.
As the Public Health Emergency ends, high levels of vaccination, combined with widespread population immunity and available treatments, have significantly reduced the risk of severe illness, hospitalization, or death from COVID-19. These factors have also contributed to the reduced need for the WA Notify application.
The Washington State Department of Health (DOH) encourages people who test positive for COVID-19 to continue anonymously notifying others via the app through May 11. After that, users will no longer receive notifications they were near someone who tested positive for the virus.
User privacy is protected, and no GPS locations or personally identifiable information was collected or stored by the application. On May 11, or soon thereafter, WA Notify users may receive a notification on their phone alerting them the tool will be disabled. N
either Android nor iPhone users will need to take action, although Android users may uninstall the WA Notify app if they choose. Beyond May 11, DOH encourages people who test positive for COVID-19 to tell their close contacts that may have been exposed to the virus.
